What ever does happen on or around the 15th will affect both delta and song. Assuming that they continue to fly, I would advise checking your flights often. We are flying from bos to mco on the 14th and hopefully returning on the 23rd. I bought the tickets last August and I can't count how many flight and time changes there have been. Each time they changed the flight, even by a minute, they would drop our seat assignments. I always contacted them and got them back, but I was watching closely and probably contacted them shortly after the changes were done. There are other people who have posted that they were unable to get their seat assignments back and need to try to get seats at check in. So keep a watch and hope for the best for all of us with delta/song tickets.
